INTRODUCTION AND OVERVIEW
INTRODUCTION AND OVERVIEWLiquid-liquid extraction is a process for separating the components of a liquid (the feed) by contact with a second liquid phase (the solvent). The process takes advantage of differences in the chemical properties of the feed components, such as differences in polarity and hydrophobic/hydrophilic character, to separate them. Stated more precisely, the transfer of components from one liquid to the other is driven by a deviation from thermodynamic equilibrium, and the equilibrium state depends on the nature of the molecular interactions between the feed components and the solvent. The potential for separating the feed components is determined by differences in these molecular interactions.A liquid-liquid extraction process produces a so…
